UAD 3.6 Overview

What is UAD 3.6? 
 

UAD 3.6 is a comprehensive update to the dataset behind appraisal reports submitted to Fannie Mae® and Freddie Mac® (the GSEs). Per the GSEs’ Lender Readiness materials (June 2024), it replaces legacy form-driven reporting with a single, flexible, dynamic Uniform Residential Appraisal Report (URAR) driven by property characteristics and loan context—improving clarity, standardization, and data quality for lenders.

The era of form numbers like 1004/70, 1073/465, and 2055 is ending. Instead, the data that describes the subject property drives the appraisal output—not a static form type/number.

Key Changes & Benefits
 
  • Moving beyond form numbers: When ordering, lenders provide characteristics that drive the report, such as:
    • Appraisal Type: Traditional, Hybrid, Desktop, Exterior-Only, Appraisal Update, Certification of Completion
    • Dwelling Type: SFR, Condominium, Manufactured Housing, Small Residential Income Property, Cooperative Interest
    • Additional Clients/Intended Users: (e.g., bank/investor overlays; FHA, USDA, VA, etc.)
    • Property Rights: Fee Simple, Leasehold
    • Assignment Type: Purchase, Refinance, Other
    • Occupancy: Owner, Tenant, Vacant
  • Enhanced data & delivery:
    • Discrete data (less free text) → more consistent, searchable, and automatable information
    • ZIP file delivery (XML + PDF + images) rather than XML-only
    • Better photo tagging and organization
    • Improved QC via expanded fields and automated rules
    • Updated UCDP schema for submissions
    • Redesigned SSR (PDF & JSON) with more actionable feedback
Implementation Timeline 
 
  • Sep 8, 2025 – Jan 25, 2026: Limited Production with select lenders
  • Jan 26, 2026 – Nov 1, 2026: Broad Production open to all lenders
  • Nov 2, 2026: Mandate date — UAD 3.6 required for new submissions
  • May 2027: Retirement of UAD 2.6 pipeline
Steps to Prepare
 
  1. Familiarize your teams with property characteristic inputs that replace form numbers.
  2. Review systems/integrations for new data structures, ZIP packaging, and UCDP schema updates.
  3. Train underwriting/QC on discrete-data review, SSR changes, and image/tagging expectations.
  4. Coordinate with partners (lenders/investors/AMCs) to ensure cutover readiness and dual‑track support during transition.

Frequently Asked Questions

The UAD is a standardized industry dataset for appraisal property reporting that is communicated electronically through the Uniform Collateral Data Portal® (UCDP®). Fannie Mae and Freddie Mac (GSEs) are updating the UAD to create a data-driven, dynamic reporting structure to capture property and market information. The limitation of the legacy forms is that additional required data is provided in a free-form commentary addendum. This update allows for one reporting structure that accounts for all property and inspection types. As part of this initiative, the GSEs are aligning to the latest version of the Mortgage Industry Standards Maintenance Organization (MISMO®) Reference Model 3.6.

Yes, the appraisal report forms listed below are being replaced with a data-driven, flexible, dynamic structure for appraisal reporting. The redesigned Uniform Residential Appraisal Report (URAR), Restricted Appraisal Update Report, and Completion Report each have a similar look and feel to the Uniform Residential Loan Application (URLA) and the Closing Disclosure (CD).

  • Uniform Residential Appraisal Report (1004 / 70)
  • Uniform Residential Appraisal Report (Desktop) (1004 Desktop / 70D)
  • Uniform Residential Appraisal Report (Hybrid) (1004 Hybrid / 70H)
  • Individual Condominium Unit Appraisal Report (1073 / 465)
  • Individual Condominium Unit Appraisal Report (Desktop) (1073 Desktop / 465D)
  • Individual Condominium Unit Appraisal Report (Hybrid) (1073 Hybrid / 465H)
  • Exterior-Only Inspection Individual Condominium Unit Appraisal Report (1075 / 466)
  • Exterior-Only Inspection Residential Appraisal Report (2055 / 2055)
  • Manufactured Home Appraisal Report (1004C / 70B)
  • Individual Cooperative Interest Appraisal Report (2090)
  • Exterior-Only Individual Cooperative Interest Appraisal Report (2095)
  • Small Residential Income Property Appraisal Report (1025 / 72)
  • Single Family Comparable Rent Schedule (1007 / 1000) * See FAQ # 5 for more information.
  • Appraisal Update and/or Completion Report (1004D / 442)

Yes. With the new URAR, the data that describes the subject property drives the appraisal report, not a form type or number. Use the Functioning Without Form Numbers document to:

  • Help understand how the URAR’s dynamic structure along with discrete and repeatable data replaces the legacy form numbers
  • Assist with transitioning to the redesigned report

If the appraisal report was completed using a legacy form, the 1004D / 442 would be used, but if completed on the new URAR, the new Completion Report and/or new Restricted Appraisal Update Report would be used. These are now individual reports, each with their own accompanying specification. Refer to Appendix D-2 and D-3 for examples of the new reports.

In most situations, estimating the monthly market rent will be part of the appraisal assignment and included in the new URAR under the Rental Information section.

When the need arises to establish a monthly market rent after the URAR has been completed, then the original appraiser must be engaged to amend the original URAR to include the Rental Information section.

In rare cases, the original appraiser will not be available to amend the appraisal report. In this situation, a different appraiser may complete the Single-Family Comparable Rent Schedule to satisfy the requirement for the loan. Please note, this form was never designed to be a standalone appraisal report and the alternate appraiser completing it must take the necessary steps to be compliant with the Uniform Standards of Appraisal Practice (USPAP).

Yes. UAD 3.6 supports traditional, hybrid, desktop, and exterior appraisal assignments. Refer to the GSE Selling Guides for specific policies.

No. In place of the General Addendum, there are specific fields within each section of the URAR that allow commentary to be added as necessary, offering the appraiser ample room to provide additional information.

Yes. The purpose of the URAR has not changed. The opinions, conclusions, and certifications in the appraisal report are for the intended user to evaluate the property that is the subject of the appraisal for a mortgage finance transaction or related activities.

Yes, the GSEs have worked closely with the government agencies – Federal Housing Administration (FHA), United States Department of Agriculture (USDA), and the Department of Veterans Affairs (VA) – to include their specific requirements in UAD 3.6. Contact each agency for their implementation plans.

UAD 3.6 provides standardized data fields and enumerations to define the property, helping lenders and other end users better understand the property’s characteristics to verify property eligibility and determine overall collateral risk.

No, these appraisals are not in scope of the UAD and Forms Redesign project.

The appraiser, through their appraisal software provider, has the ability to run the UAD compliance rules through an API. Fannie Mae and Freddie Mac created UAD Compliance APIs to evaluate the XML for compliance with the UAD Delivery Specification. The rules check for data completeness, validity (format and data type), and reasonableness.

The UAD Compliance API does not include Loan Collateral Advisor® or Collateral Underwriter® messages or findings, such as eligibility, risk scores or appraisal quality.

To see a full list of the rules that are run by the UAD Compliance API, download Appendices H-1, H-2, and H-3.

For lenders that deliver loans to the GSEs, the ULDD Phase 5 update includes enhancements to align ULDD property data points with UAD 3.6. These updates must be implemented by July 28, 2025. For more information, see the Fannie Mae and Freddie Mac ULDD webpages.

The Condition and Quality Rating scale has not changed, but definitions were rewritten to provide clarity and make it easier to distinguish between the ratings. Interior and Exterior Condition and Quality Ratings have also been added for a distinction when there are significant differences in the condition status between interior and exterior. See Appendix 2 of the URAR Reference Guide or Condition and Quality Rating Definitions for details.

Yes, the Condition and Quality Ratings apply to all residential property types, including manufactured homes. This is a change from UAD 2.6.

This helps support the Condition and Quality Ratings.

Yes. New construction will now be reported as Fully Updated instead of Not Updated. See the URAR Reference Guide for details.

  • Room Update Status (Kitchens and Baths)
  • Overall Update Status for Bathrooms
  • Overall Update Status for Flooring

This depends on whether it was original construction covering multiple years or additional construction done years later.

Example 1: Dwelling was started in 2024 and completed in 2025. The year the structure was completed (2025) would be reported.

Example 2: Dwelling was originally built in 1950, with an addition constructed in 2002. The year of the original part of the structure (1950) would be reported.

The URAR includes more detailed information about ADUs, such as size, condition, rooms, and location. ADUs display in a more consistent manner on the new URAR than on the legacy forms, which will make it easier for reviewers to identify. See the URAR Reference Guide for details.
